My first Breeze had this trouble after flying through one battery on many occasions. It was due to an overheating problem. My replacement Breeze will fly through all three of the batteries I have for it without overheating, but if it sits powered up and connected without moving for six or seven minutes it will drop connnection and I’ll have to let it cool.
You should contact Yuneec CS at
Yuneec USA | Support, and choose Speak with a Pro. Try the Live Chat and if you are not able to get through that way after several tries use the Schedule Phone Support and choose an opening that fits your schedule.
I strongly suspect you are having thermal troubles with your Breeze and if you are within the 1 year warranty period they will take care of it.
